SHRED ER or Bug A Salt? Which to buy?

After posting previous video (unboxing and review of SHRED-ER, See link below), I received questions regarding which Bug-A-Salt product would be best to purchase. I try and go over some of the positives and negatives of each product to best allow you to come to the decision of which product would be best for you. I include some tests shots on window screening and furniture simulating surfaces.
